INSIGNIA LABS WATER LEVEL INDICATOR & OVERFLOW ALARM SCHOOL COLLEGE PROJECT KIT(Multicolor)

This is a FULLY ASSEMBLED PROJECT KIT & 100% WORKING. The project includes three probes which are submerged in water tank at ¼, ½, full level. One probe is connected to base of water tank to +9v. Based on the water level the probes will send signals to individual transistor which will in turn switch on respective LEDs for indication. As soon as the tank is full, all the LEDs will glow and the buzzer/alarm will be turned on
